He does come out with some brilliant episodes from time to time. But I do sort of agree. There was a lot more consistency when Davies was writing. Some of the episodes just seem to be filler. ie. Series 7 (not including asylum of daleks or angels take Manhattan) he seemed to be waiting for them to leave before getting on with the new series. Don't get me wrong, they were still good, I just didn't think they were as good as previous episodes. (Although to be fair, moffat only wrote Asylum and Angels)
